Abstract: Modern soil sample preparation using an ultrasonic treatment for 20 minutes was performed by acid decomposition of the sample. The influence of surfactant concentration and ultrasound on the sensitivity of atomic absorption determination of Manganese and Iron has been studied. It was found that the most significant increase in sensitivity is achieved by adding Triton X-100 (w = 4%). It was also investigated that the sensitivity of the determination increased: for Manganese - 1.37 times, for Iron - 1.33 times. The content of Manganese and Iron in the soil near the gas production well was determined by atomic absorption, atomic emission with inductively coupled plasma, and X-ray fluorescence methods using manganese and iron acetylacetonates as standard samples of the composition. The correctness of the atomic absorption determination results of analytes was checked by the "introduced-found" method. By varying the weight of the sample, it is shown that the systematic error is insignificant. A comparison of the results obtained by an independent method of analysis was made. It appeared that the scatter is not remarkable and is caused by a random scatter. The limit of detection of Manganese (Cmin = 0.001 ?g / ml) and Iron (Cmin = 0.008 ?g / ml) was estimated as the ones below of the literature data.
Key words: Manganese, Iron, atomic absorption, atomic emission with inductively coupled plasma spectrometry, X-ray fluorescence analysis, ultrasound, Triton X-100, sample preparation, metrological characteristics.
